UNITED STATES PATENT o E 4 Claims.

This invention relates to bathing apparatus and more particularly to a combined circular shower bath and mechanical massage device.

The object of the invention is to provide a combined device of the character described of simple and inexpensive construction capable of being readily installed in a bath room or other desired place and which can be used with equally good results either as a shower or Turkish bath or for massaging the body.

, A further object of the invention is to provide a bath of circular contour with the mechanism for operating the massage element disposed on the outside of the tub so as not to interfere with the bathing operation and with the valve and electric switch for controlling the water and heat arranged within convenient reach of the bather.

A further object is to provide a novel form of thermostatic control valve interposed in the hot and cold water supply line and so constructed as to automatically cut off the supply of water to the tub in case the temperature of the water becomes too hot thereby effectually to prevent accidental scaldingv of the bather and render the bath perfectly safe for children as well as grown-ups.

A still further object of the invention is generally to improve this class of devices so as to increase their utility, durability and efficiency.

In the accompanying drawings forming a part of this specification and in which similar numerals of reference indicate corresponding parts in all the figures of the drawings:

Figure 1 is a vertical sectional view of a combined circular bath and mechanical massage device embodying the present invention,

Figure 2 is a rear elevation,

Figure 3 is a vertical sectional view of the thermostatic control valve, and

Figure 4 is a side elevation of the valve, a por tion thereof being broken away to show the construction of the operating means.

The improved circular shower bath and mechanical massage apparatus forming the subjectmatter of the present invention comprises a vertically disposed tank or tub 5 preferably circular in cross section and closed at its top and bottom, as indicated at 6 and I, the front wall of the tub being provided with an entrance opening 8 defining an upstanding lip 9 at the base of the tub to prevent the escape of water therefrom.

Secured to the inner wall of the tub 5 is an arcuate supporting rod II! on which is slidabiy mounted one or more curtains formed of any suitable material and which curtains, when drawn, serve to close the opening 8 and prevent splashing of the water when taking a shower bath and confine the heat therein when taking.

a Turkish bath.

charge and arranged directly above the drain pipe is a stool I3 on which the bather may sit when bathing.

Disposed at the top 5 of the tub is a heater ll of conventional construction and which mayKbe used either for drying the hair after taking a' bath or for heating the interior of the tub when the device is used as a Turkish bath. Connected with the electric heater I4 is an electric switch l5 having one or more push buttons operatively connected with suitable resistance coils (not shown) within the heater so that by pushing one or the other of said buttons the intensity through which they water is sprayed onto the bather.

Arranged on the outside of the tub or tank 5 and secured thereto-in any suitable manner is a bracket l9 on which is mounted an electric motor 2|) having a relatively small pulley 2| for engagement with a drivebelt 22; The belt 22 extends over a relatively large ball bearing disk or pulley 23 mounted for rotation on a supporting stud 24 secured to the tub in vertical alinement with the motor 20. Extending laterally from the disk or pulley 23 is a crank pin 25 and pivotally mounted on said pin is a connecting rod 26 preferably formed in two sections having their adjacent ends pivotally united at 21. Secured to the tub below the disk or pulley 23 is a bracket or support 28 having'a threaded socket 29 formed therein and provided with a terminal laterally extending flange 30. Coacting with the bracket 28 is a guide member 3| preferably in the form of a circular disk having a threaded shank 32 for engagement with the threads 29 on said bracket. The member 3| is provided with a vertically disposed slot 33 flan e 30 or a w to turn freely n t passage of water through the valve, as previously threads 29. stated; The seating of the valves 53 and 54 may The lower section of the connecting rod 2| is be adjusted to a nicety by rotating the fingerprovided .with a terminal socket 34 which receives piece 60 which, in turn, raises or lowers the the adjacent end of a curved spring 35, the oppobushing 49 thereby rendering the valve very sensite end of which extends through spaced loops S ive in Operation.
